The most-traded June copper contract on the Shanghai Futures Exchange climbed 0.6 percent to 60,100 yuan ($9,500) a tonne on Friday. "This week copper has been highly correlated with equity markets, so even if prices can rebound on China's official PMI data, I think it will be capped, maybe around $8,600 per tonne," said Bonnie Liu, a Macquarie analyst in Shanghai.
